Part Details:

SN54/74LS132 QUAD 2-INPUTSCHMITT TRIGGER NAND GATE The SN54 / 74LS132 contains four 2-Input NAND Gates which accept stan- dard TTL input signals and provide standard TTL output levels. They are ca-pable of transforming slowly changing input signals into sharply defined, jitter- QUAD 2-INPUT free output signals. Additionally, they have greater noise margin than SCHMITT TRIGGER NAND GATE conventional NAND Gates. Each circuit contains a 2-input Schmitt trigger followed by a Darlington level LOW POWER SCHOTTKY shifter and a phase splitter driving a TTL totem pole output. The Schmitt triggeruses positive feedback to effectively speed-up slow input transitions, andprovide different input threshold voltages for positive and negative-going tran-sitions. This hysteresis between the positive-going and negative-going inputthresholds (typically 800 mV) is determined internally by resistor ratios and is J SUFFIX essentially insensitive to temperature and supply voltage variations. As long CERAMIC as one input remains at a more positive voltage than VT+ (MAX), the gate will CASE 632-08 respond to the transitions of the other input as shown in Figure 1. 14 1 LOGIC AND CONNECTION DIAGRAM DIP (TOP VIEW) N SUFFIX VCC PLASTIC 14 13 12 11 10 9 8 CASE 646-06 14 1 D SUFFIX SOIC 14 CASE 751A-02 1 1 2 3 4 5 6 7 GND ORDERING INFORMATION SN54LSXXXJ Ceramic SN74LSXXXN Plastic SN74LSXXXD SOIC 5
